Retention of three brightness discriminations by rats following posterior cortical lesions Tryggvason , Svavar
Abstract
Rats were trained on one of three brightness discriminations. In one task, the discriminanda differed in both luminance and luminous flux. In the second task, the discriminanda differed only in terms of luminous flux. In the third task, the discriminanda differed only in terms of luminance. Following acquisition, half of the animals on each task underwent removal of the striate cortex. Retention tests indicated that a discrimination based on flux cues was relatively undisturbed following striate removal, whereas a discrimination based on luminance cues appeared to be permanently lost. Transfer discrimination tests indicated that deficits other than sensory impairments may follow striate ablation. Results are discussed in terms of sensory and attentional deficits which occur with striate removal.
